How to reset the settings to factory on Xiaomi Redmi 3S

Smartphone Xiaomi Redmi 3S — legendary budget, which even after years of service can surprise with its performance, but over time, the operating system MIUI can begin to work unstable. The accumulation of temporary files, conflicts of installed applications or software errors often lead to the fact that the device begins to slow down, spontaneously restart or completely stop responding to user commands. In such situations, the only effective solution is a complete reset of the system, which will return the gadget to the state “out of the box”.

The data cleanup procedure does not require deep technical knowledge, but it requires care and compliance with certain security rules to avoid turning a useful tool into a brick. Before you start taking decisive action, you need to clearly understand that Hard Reset irretrievably removes all user information: contacts, photos, music and logins from accounts, which is why preparation is a critical step, the neglect of which can lead to the loss of valuable data forever.

In this article, we will take a look at all the available ways to restore the factory state of your Redmi 3S, look at the nuances of working with Recovery mode and answer the frequently asked questions that owners of this model have. We will also discuss how to properly prepare the device for the procedure so that it goes as smoothly and safely as possible for the hardware of the smartphone.

Preparing the device for a complete data reset

The first and most important step before starting any manipulation of system files is to create a backup. Xiaomi owners have several handy tools for this, including an integrated Mi Cloud cloud or local saving to an SD memory card. Go to the Settings menu → Advanced Settings → Memory and select Backup to save the folder structure and application settings.

Make sure that the battery is at least 50-60%, as the partition formatting process can take 10 to 30 minutes depending on the amount of information accumulated.

• 📱 Make a backup of your contacts and SMS Google or Mi Account account.
• 💾 Copy important photos and videos to your computer or cloud storage.
• 🔋 Charge your smartphone to at least 60% before the procedure begins.
• 🔓 Turn off the lock screen (pattern lock, PIN-code) if you plan to reset via the menu.

Remember to unplug your Google account if you plan to transfer your device to another owner, although if you completely reset your account through the menu, your account settings are automatically deleted. However, in the event of a crash when you reset through Recovery, FRP (Factory Reset Protection) may request the last Google account you used, which will be a problem if you do not remember them.

Resetting settings through the standard MIUI menu

The safest and easiest way to get the Xiaomi Redmi 3S back to its original state is available directly from the operating system, which is suitable for cases when the smartphone is turned on, the screen responds to touch, and you have access to the main settings menu. The action algorithm is standardized for most versions of the MIUI shell, but the names of items may vary slightly depending on the firmware version.

To start, open the Settings app and scroll down to the bottom of the About Phone section, where the basic system management tools are hidden. Select Reset, and then the system will alert you to the consequences of this operation, and you will be offered two options: Reset all settings (saving files) and Clear all (full waiver).

💡

Before clicking the Clear All button, take a picture of your current Wi-Fi network settings and passwords if you don’t remember them by heart, as it will be impossible to restore them after resetting.

Select the “Clear All” option to delete all data. The system will request confirmation of action, often requiring you to enter a screen unlock password or password from your Mi Account for security. Once confirmed, the smartphone will reboot, and the formatting process will begin, which visually looks like a download with the Mi logo and a progress scale.

⚠️ Warning: After selecting the "Clean All" item, the process becomes irreversible. Interrupting the smartphone during formatting (for example, removing the battery if possible, or severe mechanical stress) can lead to a software failure.

The time required to complete the procedure depends on the speed of writing the built-in drive and the amount of space filled. Usually the entire process takes no more than 10-15 minutes. Upon completion, the Redmi 3S automatically restarts and welcomes you to the language selection screen, which indicates a successful operation.

Hard Reset via Recovery Mode

If the MIUI operating system does not boot, freezes on the logo or the touch screen has stopped responding, the only way out is to use Recovery Mode. This is a special diagnostic environment built into the device’s memory that allows you to perform low-level maintenance operations on the smartphone regardless of the state of the main OS.

To enter this mode on the Xiaomi Redmi 3S, you need to turn the device off completely. Then simultaneously press the Volume Up and Power button. Hold both buttons until the Mi logo appears, then release the power button, but continue holding the volume button until the main Recovery menu opens.

Navigation in this menu is done using volume buttons (up and down), and the choice of item is confirmed by a short press of the power button. You need to find the Wipe Data item and select it. In the submenu that opens, select Wipe All Data, and then confirm the action by selecting Confirm. The system will again warn about the risks, and after confirmation, the cleaning process will begin.

💡

Recovery mode is the only way to restore the smartphone if it stopped loading or got stuck on the manufacturer’s logo.

After the cleaning process is completed, which can take a few minutes, the top corner of the screen will show the words "Data wiped successfully." Now you need to select Reboot, then Reboot to System. The smartphone will restart and begin the first, usually longer, boot of a new clean system.

Reset via Mi Cloud (remote method)

In situations where the Redmi 3S smartphone is lost, stolen or locked with an unknown password, but is connected to the Internet and has a Mi Account activated, you can use a remote reset, this method requires access to a computer or other device with access to the network and knowledge of the username and password from the Mi Account.

Go to the official Mi Cloud website and log in to your data. Search the Find Device interface. If your smartphone is online and geolocated, you'll see its location on the map. The action you can take is the Wipe Data button.

When you press this button, a command is sent to the server, which forcibly initiates the formatting of the device. Xiaomi Redmi 3S must receive the signal and automatically reset, even if it is in sleep mode. This is an effective way to protect personal data from unauthorized persons, but it requires a preliminary setup of synchronization.

• 🌐 Requires an active Internet connection on a smartphone (Wi-Fi or mobile data).
• 🔐 You need to know the password from the Mi-account associated with the device.
• 📍 The “Device Search” function must be enabled in the account settings in advance.
• ⏳ The process may take time until the device communicates with the server.

⚠️ Note: Remote reset via Mi Cloud does not always work instantly. If the device is off or out of network coverage, the command will only be executed when it is connected to the Internet.

Solving problems after reset (Bootloop and errors)

Sometimes, after the Hard Reset procedure, users are faced with a problem when the smartphone endlessly restarts, hangs on the Mi logo or gives out an error message, a phenomenon called a bootloop, most often due to damage to the system files of the firmware or conflict of residual data after the update.

The first thing to try is to reset again, but through Recovery mode, making sure that you choose the full formatting of all partitions. If that doesn't help, you may have damaged the recovery partition or bootloader, which would require a computer flashing of the device and the Mi Flash Tool utility.

In rare cases, the problem may be hardware, such as flash memory wear, which is common in budget models after years of heavy use. If flashing doesn't solve the problem, it's likely that the memory chip or (motherboard) will need to be replaced at the service center.

It is important to distinguish between software failure and physical failure. If after resetting and trying to flash the phone behaves unstable, warms up in the area of the processor or makes extraneous sounds, further independent experiments can only make the situation worse.
